The following scenario illustrated to me that I do not understand enough of
what web2py is doing in the background.
I want a crud.read form and a link to edit the same form (see the two
functions below). At first I wanted to use the link
like this:
link = A('Edit', _href=URL(c='default', f='edit_journal',
vars=request.vars(0))) but web2py would not accept that.
I have then changed it to what is shown below.
def edit_journal():
opskrif = T('Editing journal record no. %d') % int(request.vars.id)
vorm = crud.update(db.akb_journal, request.vars.id,
deletable = False,
next = URL(r = request,
c = 'default' ,
f = 'articles',
args=request.args))
return dict(vorm=vorm, opskrif=opskrif)
def show_journal():
opskrif = H1(T('Journal record no. %d') % int(request.args(0)))
vorm = crud.read(db.akb_journal, request.args(0))
link =
A('Edit',_href=URL(c='default',f='edit_journal',vars=dict(id=request.args(0))))
return dict(vorm=vorm, opskrif = opskrif,
link=link
)
When I first click on the link in the second function the crud.update
runs as expected in the first function.
I would expect that after submitting the form I would be redirected to
default/articles, but it does not happen.
In stead the program returns to edit journal and while the content of
request.vars was
<Storage {'id': '8995'}> the first time now it is
<Storage {'publisher': '', 'title': 'South African Journal of
Continuing Medical Education', 'issn': '1016-6742', '_formname\
': 'akb_journal/8995', 'standard_name': '', '_next':
'/akb/default/articles', '_formkey':
'f9ed441dd56941349a6e9b31fa29eff7'\
, 'abbrev_iso': '', 'id': ['8995', '8995'], 'subject': ''}>
Please take note what happened to the id field.
Now my questions:
Why does the above code not cause web2py to redirect to the 'articles'
function after submitting the form?
Why is not possible for me to use request.args in the link in the
second function?
What is the correct way to do this?
Regards
Johann
